BURlAL-VAULT.

SPECIFICATION forming part of Letters Patent No. 786,094, dated March28, 1905.

Application filed July 7, 190 Serial No. 215,672.

To all whom it may concern:

Be it known that I, FRED GEORGE BOYDEN, a citizen of the United States,and aresidentof Bradford, in the county of Stark and State of Illinois,have invented a new and Improved Burial-Vault, of which the following isa full, clear, and exact description.

My invention relates to burial-vaults and the like; and the main objectis to provide a joint for the several parts of structures made up ofplates or slabs which will be impervious to water and, moreover, will bestronger and less liable to be damaged than the joints heretofore known.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure l is a perspective view of a vault with a preferred form of myinvention applied thereto. Fig. 2 is avertical longitudinal sectionalview of the same. Fig. 3 is asectional view on the line 3 3 of Fig. 2 onan enlarged scale. Fig. 4: is a sectional view on the line 4 4 of Fig. 2on an enlarged scale, and Fig. 5 is a perspective view showing a cornerof the vault before the parts are assembled and illustrating the mannerof putting the parts together.

The side pieces or slabs constituting them are represented by the lettera, the ends by Z), the bottom by c, and the top by d. It is immaterialwhether these portions of the vault are composed of one or more slabs,but my invention comprises both structures.

Each of the slabs is provided with projections near its edges, saidprojections extending, preferably, the whole width or length of theslab, as the case may be. tions on the sides, ends, bottom, and top arelettered a, Z), c, and (1, respectively, and they are located on theexterior of the plates except on the bottom plate, upon which they arelocated on the inside.

It will be seen that at the corners of the vault the projections a andb, which are formed near the edges of the plates (a and b, will form asort of trough with the other parts of the plates, which by the aid of acouple of boards or similar device placed upon the cor- These projecnerof the vault and exterior to the projections (4 and b will be adaptedfor the reception of the plastic material to form a joint 0. In the samemanner the two projections (0 upon the sides, when the latter arecomposed of a plurality of plates or slabs a, will form a trough, whichby the aid of a board placed across the outer faces of the projectionswill provide for a trough or opening into which plastic material maybepoured to form ajoint f. In a similar manner joints g between the topslabs and the side slabs may be formed of plastic material, and otherjoints g between the several slabs of the top and g between the slabs ofthe top and ends. It will be obvious that these various joints willclose the openings between the various slabs of which the vault iscomposed and that they may be very easily made by simply placing boardsagainst the various projections on the slabs and pouring plasticmaterial between them and the projections. It will be observed thatthese plastic joints thus formed are located on the outside of theopenings or spaces between the slabs which they are designed to close,and consequently any pressure of water or earth upon the outside of thevault will not tend to force the plastic joint away from the slabs, butto force it into closer contact therewith. The co'rner-joints are shownas being provided with pins a and b projecting from the side pieces andend pieces, respectively. These pins enter the plastic material or aresurrounded thereby and thus aid in holding it in position and add to theefficiency of the joint. It will be further observed that at certainpoints projections suchas those mentioned are not needed-as, forexample, at the joints formed between the top and the sides and ends.Here the sides and ends are recessed at a and b ,respectively,to formshoulders upon which the top (Z is adapted to rest. The place for theplastic material is then formed between the projections d on the top andthe upwardly-extending portion of the walls a or b, as the case may be.

The bottom 0 of the vault is constructed in a slightly different manner.The joints it are here made on the inside of the vault, if desired,between the projections c 0, and a joint Z; is preferably formed betweenthe end projections 0 and the end wall 7) of the vault. Similar joints7: are formed between the side projections c and the side walls a. Inorder to provide additional security for these joints around the bottomof the vault,the side pieces a and end pieces 7) are provided with smallprojections a and 7/, respectively, while the bottom slabs are providedwith grooves 0 adapted to register therewith; but the grooves are largerthan the projections and the space between them is filled with plasticmaterial to form the joints Z and Z.

It will be apparent that a very strong joint is thus obtained and onethat will resist the pressure of water from the outside and last muchlonger than any joint heretofore known.

While I have illustrated and described a particular and preferred formof my invention, it will be obvious that modifications may be madetherein, and I do not wish to be limited to the exact details shown anddescribed.

Having thus described my invention, I claim as new and desire to secureby Letters Patent 1. Areceptacle having vertical walls formed with slabsmeeting each other at right angles at the corners of the receptacle,each of said slabs being provided with a vertical outwardly-extendlngpro ection near its edge and a series of pins extending from saidprojeotions in a direction parallel with the plane of the faces of theslab, and a filling of plastic material introduced between the adjacentprojections of the two slabs at the corner of the receptacle, saidfilling surrounding said pins and constituting the outside corner of thereceptacle.

2. The combination of a plurality of slabs forming the top, bottom, sideand end walls of a receptacle, said slabs being provided with externalprojections near their edges, a series of pins extending outwardly fromthe edges of said slabs in a direction parallel with the plane of thefaces thereof, and plastic fillings between each two adjacentprojections, said slabs forming the sides and ends each having aprojection along the bottom thereof, and said slabs forming the bottomhaving grooves near their edges larger than said last-named projections,for the reception of said projections, and a filling of plastic materialin said grooves and surrounding said projections.

In testimony whereof I have signed my name to this specification in thepresence of two subscribing witnesses.

FRED GEORGE BOYDEN.
